PEESSER FOOT FOR SEWING MACHINES.

Application filed June 3,

a sewing machine for guiding and holding down a bottom welt strip to the sole of a shoe when said welt is sewed to the shoe. The invention consists broadly of a presser foot provided with a vertical opening through the foot proper, and in which is adapted to be reciprocated an awl and a needle, and a horizontal opening which is located in the toe of the foot, and is sub stantially rectangular in shape, which opening isadapted todirect the welt strip into position onto the sole of'the boot or shoe, and into the pathof the needle and awl, so -that-asthe welt strip receives the sole attaching stitches and is sewed to the sole, the sole is likewise sewed to the upper part of the shoe. i

The presser foot is adapted to not only hold the strip when the awl and needle are inserted through the same, but also to guide the strip along the shoe, where it is forced into position on the margin of the sole and into the attaching line as the operation'of sewing the sole progresses. The said presser foot serves together with the manipulation of the shoe by the hand of the operator to bend the tread welt sidewise without buckling the same, as the 40 sewing proceeds around the bends or grooves, particularly while traveling around the toe, or in making a turn when sewing from the shank to the ball of the sole. A guideway of the presser foot maintains the strip in proper position relatively to the needle and awl.

The presser foot also may be used in plain sewing of the sole without the addition of the welt strip.

The invention will be best understood from a consideration ofthe following detailed description taken in connection with the accompanying drawing forming part of this specification, with the understanding, however, that the invention is not confined to any strict conformity with the .showing in the drawing,

but may be changed and modified so long as such changes and modifications mark no material departure from the salient features of the invention as expressed in the appended claims.

In the drawings Fig. l is a side elevation of the presser foot secured to the operating arm of a seiw ing machine, with the shoe shown in dotted lines in front of the presser foot.

Fig. 2 is a front elevation of the presser foot.

Fig. 3 is a foot.

Fig. is a view in perspective of the presser foot proceeding towards the toe of a shoe when the shoe back of the presser foot;

In the drawings, 1 designates a wore rest or table, an awl, and 3 a needle. A presser t is secured to the presser ear 5 of. the I, ng machine by means of screws which are inserted into threade nerfora- 8O tions which at rigl angles to ash other vertical section of the presser in the shank of the presser foot. The awi 2 and the needle 3 are operated. by .he usual sewing machine mechanism .or reciprocat these parts The shank of the presser foot is gradually diminished in size at a point where the shank joins the foot The foot 8 comprises a toe 9, the straight sided portion 10 having a slightly depressed portion 11 which is adapted to engage the side of the shoe, and a rounded bulging longitudinal side 12. An opening 13 running longitudinally of the foot and extending vertically through the foot is enclosed by the toe 9 and the sides 10 and 12 and the heel let of the foot. The upper longitudinal edge is cut away or beveled at 15' A v the point where the side 1?; joins the shank 7, a guide way 16 is formed over which thread. may be drawn This guideway 13 finished by polishing or is made exceptionally smooth in order that a thread will not be broken or injured as it passes over this guideway.

The base 1 of the foot 8 is inclined upwardly from the heel to the toe and has side flanges 18 and 19 depending from its periphery, receding rearwardly to the heel and connected together by a front flange 20 depending from the toe of th presser foot, in which is located the horizontal slot 21, and through which is adapted to be inserted and guided by the flanges l8 and 19, a welt 22 which is wound upon the spool .23 secured in any suitable manner to the sewing machine.

A thread which proceeds from a reel rotatably mounted on the machine is directed to the vertical openin 13 in the presser foot, and is adapted to be caught by the needle 25 and pulled through an opening in the welt and the sole of the shoe, which opening was previously made by the awl E2.

The operation 01. my device is as follows: In Fig. l the presser toot that guides the welt 29 is shown in position behind a shoe, which is shown indott d lines, The welt is drawn from the spool through the hori- Zontal slot 21 and guided by means oi the flanges l8 and 19 of the presser :ioot towards the toe oi the shoe and along the edge of the sole, while the ewl is reciprocated in the vertical opening 13 to perforate the welt 22 and the sole in order that the thread F J-l may be drawn through the perforations made by "the awl and complete the sewing operation.

The presser toot, as is the case in all machines of this kind, is adapted to be reciprocated upwardly and downwardly, and by these movements combined with the feeding of the work serves to force or crowd the welt strip gradually and fully into its proper place on the edge oi the sole.

The awl operates close to that part of the opening which is nearest to the toe of the presser toot. its the presser root descends onto the work for a new stitch, it carries forwardly with it the welt towards the toe and guides the same in its proper position on the tread of the sole.

What is claimed is 1. A pressure toot for guiding welts to be sewed on shoes, comprising a shank, a, foot proper divided with a vertical opening with the bottom of the foot inclined rearwardly from the toe to the heel, a flange depending from the toe and extending rearwardly along the side edges of the bottom of the foot and gradually decreasing in height to a point midway betweenthe heel and toe where the flange merges into the bottom 01'' the foot, the portion of the flange depending from the toe being provided with a horizontal slot for receiving the welt and opening into an inclined 'uideway tor the welt'i'ormed by the depending flange and the bottom of the foot, the bottom edge of that portion of the flange depending from the toe being adapted to engage the part of the shoe to be sewed, with the unfimged bottom por-v tion of the root forcing the welt into engagement with that part of the shoe being sewed.

2. A pressure foot for guiding welts to be sewed on shoes, comprlsing a shank, a foot proper provided with a vertical opening, with the bottom of the toot inclined rearwardly i'rom the toe to the heel, a flange depending from the toe provided with a horizontal slotto receive and hold the welt, with the bottom edge oi? the flange resting on that portion of the shoe which is being sewed, while the bottom portion ofthe foot which is adjacent 'the heel is adapted to torce the welt into engagement with the part of the shoe to which the welt is being applied, the vertical opening in the foot being located between these two engaging portions or the foot.- r

In testimony, that I- claim the foregoing as my own, I have hereto aflixed my signature.
